FASTENER-SETTING MACHINE.

latented July 9, 1918.

Application filed August 20, 1914. Serial No. 857,760.

To all whom it may concern:

Be it known that I, FRED A. RUMNEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description, in con nection with the accompanying drawings, is a specification, like-reference characters on the drawings indicating like parts in the several figures.

This invention relates toimprovements in machines for inserting fasteners, such as eyelets, lacing hooks or the like, in two su perposed pieces of sheet material, as for example, two quarters of a boot or two sides of a corset.

In work of this character it is important that the corresponding eyelets set in the two parts of the material shall be located exactly opposite to each other and consequently it is necessary to insure that each part of the work has imparted to it feeding movements of exactly the same extent. This is particularly important in the case of work wherein a long line of eyelets is to be set, as in corsets, for if the feeding movements imparted to one part of the work vary ever so slightly from the feeding movements imparted to the other, the cumulative effect of such difference is objectionably apparent when the end of the line of eyelets is reached. An important object of the present invention is to provide improved means for guiding two pieces of sheet material as they are fed into setting position whereby the accuracy of the feeding movements is improved and uniform spacing of the eyelets in both pieces of work insured. V

In duplex machines, as heretofore constructed, a guide plate has been employed having separate presser members for yieldingly holding the respective pieces of the work against its opposite sides. With such construction, it has been found diflicult to secure an exactly uniform tension upon the two parts of the work and the result has been that one part is retarded .more than the other so that the feeding steps have been slightly shorter in one piece than in the other. This is probably due to the fact that the work supporting plate has been disposed in a substantially horizontal position so that the weight. of thelowerpiece of material has tended to separate the lower presser member from the under side of the guide plate and so lessened the tension, whereas the weight of the material on the upper side of the guide plate has had the opposite effeet.

I have discovered that uniform feeding movements of both parts of the work may be secured by providing a pair of oppomovement to the settingposition. When the two parts of the work are thus held in contact with each other the resulting friction between their surfaces tends greatly to prevent unequal feeding of the respective pieces. Such construction is also advantageous in that it eliminates the unequal retarding of the respective parts of the work which has been found objectionable heretofore.

While the present invention relates particularly to machines for operating upon two pieces of sheet material at the same time, it is believed that work guiding means mounted for bodily yielding movement in a direction at right angles to the plane of the work have never been employed in any fastener setting machine whatever and such construction constitutes broadly an important feature of the invention.

The features above discussed and others incident to the invention will be best under stood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which Figure 1 is a view in perspective of portions of a duplex eyeleting machine having the present invention embodied therein,

Fig.2 is a similar view showing parts of the machine in a different position and showing also a portion of the work, and

Fig. 3 is a sectional view through the work guiding means and adjacent parts-of a machine.

The general construction of the duplex eyeleting machine is disclosed in Letters Patent of the United States No. 934,066, granted Sept. 14, 1909, on an application of Goddu and in the present drawings only such portions of that machine are shown as 7 are necessary to the understanding of the in en ion.

The machine frame 2 carries a normally stationary elongated guideway 4 which supports the work and directs it to ward the setting position, the edges of the work being guided by a flange at the rear side of the guideway.

The operating tools. of the machine are carried in a movable head or frame 6 which is pivotally mounted on a journal 9 in a lever 8 mounted on the machine frame. The head 6 has imparted to it movement from front to rear in order to locate successively the punches and the setting tools in the proper position to operate upon the work, and also a transverse movement for feeding the work while the setting tools engage it.

'The mechanism for moving the head 6 is not herein shown, as. it forms no part of the present invention. The head 6 has an upper and a lower branch in each of which there are two parallelbores. The setting, dies 10'are slidably mountedinthe front portion of the head 6. and the punches 12- are mounted at the rear of the setting'die. A pair of actuating levers 18 (only one of'which is shown) serve to operate successively the punches and the setting dies. The head 6 also carries a thin curved die plate, 14, at the outer end ofwhich is arranged a double faced upsetting die 15, shownin Fig. 3. This, upsetting die is maintained rigidly in alinement with and cooperates with the dies 10 in clenching an eyelet in each of two pieces of' sheet. material as inthe construction of the Goddu Patent No. 934,066. In distinction from this patented construction, however, one of the punch members 12 is made tubular and the other is solid so that they act as a punch and die in perforating the work. The punches are arranged opposite to the space formed by theconcaved curve of the die plate and in this space the punching operation takes. place.

Between the inner end of the guideway 4 and the point at which the punches operate is located a pair of work guiding members 16. The members 16 are beveled, as shown in Fig. 3., on the. edges. disposed'toward the oncoming work and are ribbed on their adjacent faces. to prevent the work from sliding outwardly and away from the-gaging flange ofthe guideway 4. Each member 16 isv secured to. and carriedby a leaf s ring 17.. The rear ends of the springs 1 are secured to. a slidable block 19 which is carried by the machine frame 2. The construction of the springs 17 is such as to hold the proximate faces of the members 16 normally in contact and yieldingly tends to prevent their displacement while permitting them to separate sufficiently to admit the passage ofthe work.- 1

The block 19 is provided with rack teeth WlliChiQHlQSll with a segment 18-:and by swinging this segment the block 19, together 1 with the guideway 4 and the members 16 may be moved forwardly or rearwardly at right angles to the line of feed for varying the spreadof the eyelets or their distance fromthe edge of the work.

i In operating the machine, the two parts 80 of the work are superposed, as. shown in Fig. 2, and their edges laid together and against, the flange of the guideway 4. The work is then pushed toward the left between the two guide members 16yuntil the point at which the first eyelets are to be setv is located in alinement with. thepunches 12. -VVhen the machine is. started, the punches are at 7 setting dies 1O and the upsetting die 15 into alinement with the previously punched holes. The head 6 inthis rearward movement, carries with it the curved die plate 14, and the pieces of work, held stationary by the work guiding members 16, are separated by the thin plate 14 so that the double-faced upsetting die15, which is always maintained in alinement with the dies 10, is brought into alinement with the punched holes ready for the setting of the eyelets. Up to the time of their separation by this plate 14, the two parts of the work have] remained in con tact. The levers 13 are then operated a second-time andan eyelet is inserted through each piece of work and clenched against the moved toward the left, being guided in its path by theroller 5 which runs. in a guide- Iway 7 In this; movement the work is drawn between the guiding members 16 which press the two pieces together and so exert an equal retarding effectv uponeachpiece, with the result that a uniform feeding movement is imparted to themboth. In Fig. 2 the machine is. illustrated with its parts in the positions occupied at the end of one feeding movement. As the, machine continues: to operate, the setting dies 10 are retracted, releasing the work so that the head 6: may be moved back to its initialposition and the operations repeated.

It will be apparent that the shape. and construction of the guiding-members: 16 may be varied widely, it bein-g'necessary only that 1. A duplex fastener setting machine, having in combination oppositely disposed pairs of setting dies, hand work guiding means constructed and arranged to press two pieces of material into engagementwith each other and guide them toward setting position.

2. A duplex fastener setting machine, having in combination, oppositely disposed pairs of setting dies, work guiding means constructed and arranged to press two pieces of material together at one side of setting position, and means for separating the pieces as they are advanced to settingposition.

A fastener setting machine having, in combination, a guideway for two superposed pieces of work, feeding devices, means for pressing the two pieces of work into engagement with each other as they leave the guideway, and a movable work separating member located beyond the pressing means relatively to the direction of feed.

10. A fastener setting machine having, in combination, means for directing two pieces of work to setting position including yieldingly mounted members for pressing the two pieces into contact with each other, punching devices arranged to punch both pieces while in contact, and means for separating the two pieces after they have been punched.
